ALBERT e. KOPAGKI, or :BAY CITY, MICHIGAN, ASSIGNOR 0F ONE-HALF T0 STEVEBUDZINSKI, or B Y CITY, MICHIGAN.

BEDSTEAD.

To all whom it may concern:

Be it known that I, ALBERT Gr. KorAoKI, a citizen of the United. Statesof America, residing at Bay City, in the county of Bay and State ofMichigan, have invented certain new and useful Improvements inBedsteads, of which the following is a specification.

This invention relates to bed steads, and particularly to a head raisingdevice, whereby the head of an invalid or other person may be readilyelevated to an inclined position on the bed.

The invention consists generally of a pivoted frame which may be readilyconnected to the general bed stead frame structure and which may beswung upwardly or downwardly on its pivotal connection with the bedstead structure through the instrumentality of cooperating gearconnections between the head frame section and the bed stead structure,under the influence of a rotative movement of one of the shaftsconnected with the gear mechanisms.

With the above and other objects in view, the present invention consistsin the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawings and particularlypointed out in the appended claims, it being understood that changes maybe made in the form, size, proportion and minor details withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawings Figure 1 is a plan view illustrating my invention;

Fig. 2 is a. side elevation; and

Fig. 3 is a transverse sectional view.

Fig. A isan end View of the mechanism at one side of the bed-stead, theside rail and hinged frame of the latter being in sections.

Referrin now more particularly to the accompanylng drawings, thereference characters A and 5 indicate head and foot portions of the bedstead which are connected in any suitable manner by the side rails 6 and7, suitable casters 8 being rovided for the support of the bed stead, idesired.

My improved head section of the bed stead is indicated generally by thereference character A and consists of a U-shaped frame 9 connected atits free ends by a rod 10 which is pivotally connected at 11 (see Fig.2) with the side rails 6 and 7 of the bed stead Specification of LettersPatent.

structure. The side bars of the U-shaped head section frame A arepreferably connected by a plurality of transverse rods 12.

Bolts 13 and 11 carrying screw threads are connected to and depend fromthe U- shaped frame A and have threaded engagement in spiral gears 15and 16, respectively. These gears 15 and 16 are mounted in suitablebrackets 17 and 18 secured to and depending from the side rails 6 and 7,respectively, of the bed stead structure. The brackets 17 are eachcomposed of a. depending arm and spaced horizontally disposed,vertically alined, approximately U-shaped portions which are alsoprovided with vertically alined opening 17. The opening 17 through whichthe screws or bolts 13 and 14: pass, permit the said bolts or screws tochange their angle with the adjustment of the U-shaped frame ,9.

A transverse shaft 19 is journaled in these brackets 17 and 18 and isprovided with spiral gears 20 and 21 designed to interengage or meshwith the aforesaid spiral gears 15 and 16 so that upon rotation of theshaft 19, the threaded bolts 13 and 14: are caused to work upwardly anddownwardly in the spiral gears 15 and 16 to elevate or lower the headsection frame A on its pivots 11 according to the direction in which theshaft 19 is rotated. To facilitate rotation of the shaft 19, it may beprovided with a hand operated wheel 22 secured to one end thereof on theouter side of one of the side sills of the bed stead structure, asclearly shown in the drawings.

From the foregoing, it will be seen that I provide an exceedinglysimple, inexpensive, durable and efficient bed stead head sectionraising and lowering device.

What is claimed is:

1. A combination bed-stead, includin side rails, a head sectionpivotally connected to the side rails and arranged to lie in the planeof the same, brackets depending from the side rails and projectinginwardly and provided with openings, spiral gears confined in thebrackets and havlng screw threaded apertures, pivoted screws dependingfrom the head section and extending through the openings of the bracketsand engaging the threaded apertures of the spiral gears, a transverseshaft extending across the bed-stead and journaled in the said bracketsand having operating means at the side of the bed-stead, and spiralgears mounted onthetransverse shaftand 'rneshing with the spiral gearsof the screws for moving the same upwardly and downwardly to raise andlower the head section.

2. A bed-stead, including side rails, a head section pivotally connectedto the side rails, brackets secured to the side rails and eachcomprising a depending arm and horizontally disposed approximatelyU-shaped portions arranged in vertical alinement and provided withvertically alined slots, screws pivoted to the head section and extendinth oug the slot vo th brackets spi e gears mounted the'brackets betweenthe 15 said spaced portions and having threaded ,openings engaging thethreads of the screws,

a transverse shaft extending across the bedsteadand journaled in thesaid brackets, and

spiral gears mounted on the transverse shaft 20 and meshing with thespiral gears of the said brackets.

In testimony whereof I afiig: myrsignature.
